Where would you store this package? The pkgname must be unique in each
repository database, so you would need a community-avx2 repository.

Then it is as simple as Santiago said, just have users add the
additional repository if they need it, giving it precedence in pacman.conf.
(Except I will go one step further and say this is the *only* way.)
